[asterisk-users] Quintum DX as gateway to PSTN for Asterisk

[doki_cti]

Hello,
I try configuring Quintum DX gateway as link to PSTN for *. Now, I can dial number which is connect to Quintum, and call is diverted to *. I don't know what I should set, if I want call from SIP_phone registred in  Asterisk to PSTN via Quitnum. I set in sip.conf account for Quintum 
[sip_proxy-out]
type=peer               
outboundproxy=QUINTUM_IP   

, and changed extensions.conf. When I call from SIP Phone, I see in Quintum log, that call is received with good caller and called numbers, but I think that quintum don't how route this call (he diverte this call to asterisk). So, can you  give me advice what I should set, when I want route all calls from IP to PSTN and from PSTN to * via IP?

How set password and user for quitnum and calls from SIP? Is it posible  on Quintum or I should use for this radius? 

Regards
Doki
